How big is the Lexus RX400h?
In brief, the Lexus RX400h spans roughly 190 inches in length, about 74 inches in width, and around 66 inches in height, with a wheelbase just over 106 inches. It seats five and offers roughly 30–40 cubic feet of cargo space behind the rear seats, expanding to about 60–75 cubic feet with the rear seats folded.
The RX400h was Lexus’s first production hybrid SUV, built from 2005 through 2009. Its size mirrors the conventional RX line of the era, meaning most measurements are consistent with other mid‑size luxury crossovers from that period, with the hybrid powertrain slightly impacting cargo layout due to the battery pack.
Exterior dimensions
Here is a quick look at the outside footprint that influences parking, garage fit, and road presence.
- Overall length: approximately 190 inches (about 4.8 meters)
- Width: around 74 inches (about 1.88 meters)
- Height: roughly 66 inches (about 1.68 meters)
- Wheelbase: just over 106 inches (about 2.70 meters)
- Curb weight: typically in the several‑thousand‑pound range, depending on trim and equipment
These exterior figures give the RX400h its recognizable stance for a midsize luxury SUV while remaining maneuverable in urban settings.
Interior space and cargo capacity
Inside, the RX400h aims to balance five‑seat practicality with flexible cargo, noting that the hybrid system’s battery pack affects available space compared with non‑hybrid RX models.
- Passenger capacity: five adults comfortably
- Cargo behind the rear seats: roughly 30–40 cubic feet
- Max cargo with rear seats folded: roughly 60–75 cubic feet
In daily use, most families will find enough room for groceries, luggage, and daily gear, with the trade‑off being a slightly reduced cargo area versus non‑hybrid RX variants.
Years and size consistency
Size figures remained broadly consistent across the 2005–2009 production window. Minor packaging tweaks or trim differences could yield small deviations, but the overall exterior footprint stayed within a narrow range for the RX400h during its run.
Notes for prospective buyers
For precise measurements tied to a specific vehicle, consult the original window sticker or the official brochure for the exact year and trim level you’re considering, since production changes can cause small variances.
Summary
The Lexus RX400h offered a practical midsize SUV footprint with about 190 inches in length, roughly 74 inches in width, and around 66 inches in height, plus a wheelbase just over 106 inches. It provided five‑person seating and flexibly sized cargo space—roughly 30–40 cubic feet behind the rear seats and up to 60–75 cubic feet with the seats folded—offset by the hybrid battery layout. Overall, its size sits comfortably alongside its non‑hybrid RX peers from the mid‑2000s era.
